Emotional wound (4)
I believe the answer is:
scar
'emotional wound' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scar that I've seen before include "Permanent mark left by a wound" , "Mark left by the healing of injured tissue" , "Old wound - bare cliff" , "Mark from a wound left on the skin" , "Craggy rock formation" .)
